Project description:TMT based quantification of protein abundance and phosphorylation state for developing mouse placenta. Timed-pregnant CD-1 mice were obtained from Charles Rivers Labs and dissected at e7.5 to extract the ectoplacental cones (EPCs) and at e9.5 to obtain the placenta as described by Martin and Cockroft (Martin, P.; Cockroft, D. L. Culture of Postimplantation Mouse Embryos). Staging of the mouse embryos was done according to Theiler criteria (Theiler, K. The House Mouse: Development and Normal Stages from Fertilization to 4 Weeks of Age; Springer-Verlag, 1972.)
Project description:Many questions about the regulation, functional specialization, computational prediction, and evolution of genomic imprinting would be better addressed by having an exhaustive genome-wide catalog of genes that display parent-of-origin differential expression. As a first-pass scan for novel imprinted genes, we performed mRNA-seq experiments on E17.5 mouse placenta cDNA samples from reciprocal cross F1 progeny of AKR and PWD mouse strains, and quantified the allele-specific expression and the degree of parent-of-origin effect transcriptome-wide. We confirmed the imprinting status of 23 known imprinted genes in the placenta, and found that 12 genes reported previously to be imprinted in other tissues are also imprinted in mouse placenta. Through a well-replicated design using an orthogonal technology, we verified five novel imprinted genes that are not known to be imprinted in mouse. It appears that most of the strongly imprinted genes have already been identified, at least in the placenta, and that evidence supports perhaps 100 additional weakly imprinted genes. Despite previous appearance that the placenta tends to display an excess of maternally-expressed imprinted genes, when the full set of genes is uniformly scored as in this study, this maternal bias disappeared. Examine allelic expression in E17.5 placenta tissues from two individual samples, one from each of the two reciprocal crosses.

Project description:We generated ChIP-Seq (H3K4me1, H3K4me3 and H3K27ac) data for term human placenta. Together with RNA-Seq and epigenomic data generated for placentas of rhesus macaque and mouse, we aim to understand the evolution of gene expression and regulatory elements among the placentas of different mammalian species.

Project description:Total RNA was isolated from all the placental tissues using Trizol, and mRNA was isolated using FastTrack Kit. We used a placenta reference as a standard for all these array hybridizations. The placenta reference is a mixture of placenta mRNA with CRG.
